despite the fact that respected international human rights organizations have condemned their actions
But Russia/Putin doesn't care.
Appealing to values of universal human rights, personal freedoms and liberal democracy is to miss the point completely. In Russia these things are not even virtues. Putin - and millions of his ardent supporters - is motivated by Eurasian nationalism and collectivism. The Russian Orthodox church is an very important part of that and any group that refuses to join the party will be suppressed.
JWs are not important enough to any western government for them to receive any meaningful support against Russia. Writing letters to Russian officials about religious freedom is as useful as writing to Hitler about multiculturalism.
Things will never get better for JWS under Putin.
